STEAM-ATOMI'ZER.

SPECIFICATION forming part of Letters Patent No. 614,099, dated November15, 1899.

1 Application filed December 21, 1897. erial No. 662,860, (N d l.)

To all whom it may concern.-

Be it known that I, BRUNO WILLIBALD EMIL GRIEP, asubject of the GermanEmperor, and a resident of Hamburg, in the German Em pire, have inventedcertain new and useful Improvements in Steam-'Atomizers, (for which Ihave obtained patents in Germany, No. 88,734, dated January 15, 1896,and No. 95,400, dated January 13, 1897,) of which the following is aspecification.

The present invention relates to improvements in steam-atomizers fordifiusing steam in spray or in the form of dew to render it moreeffective in wetting the air of closed rooms in order to absorb thesensible dry heat of such rooms=for instance,- of railway-cars,theaters, and the like; and with this end in .view my invention consistsin certain novel features of construction and combinations of parts, aswill be hereinafter fully described ,Wlth reference to the accompanyingdrawing, in which the figure is a vertical section through the improvedsteam-atomizer.

Similar letters refer to similar parts.

On the walls of the respective room or apartment to be cooled or Wettedthere are arranged one or more tubes a,- communicating with a suitablesource of steam-=for instance, with the calorifiers or pipes of asteam-heating arrangement. The free extremity of the steamtube a leadsinto a chamber d of a cup-shaped connecting-piece d, carrying a suitablesteamoutlet tube 6, covered by a cap or cowl b. Extending from theconnecting-piece d and contiguous to the steam-tube a there is anotherpipe 0", designed to carry off the condensed steam or water ofcondensation formed in the connecting-piece d and outlet-tubeb whensteam is allowed to pass through them. The outlet of steam may beregulated by means of a suitable screw-down valve f,lodged in the wallof the connecting cup-piece d and fitting, with its conical orneedle-shaped stem f, into a corresponding seat 01 provided in thepartition-wall 01 By screwing the valve stem f more or less into itsseat (I the passage of a determinate quantity of steam from the tube ainto the outlet-tube bis permitted or such passage entirely out ofi,respectively.

The screw-down valve acts not only as a stop-valve, but also as asprayer or atomizer, so that the steam escapes through the space leftbetween the cowl and outlet-tube in an extremely fine atomized state forimpregnating or saturating the surrounding air with the requiredmoisture, while the condensed steam is permanently conveyed through thepipe 0".

Having fully described my invention,what I claim, and desire to secureby Letters Patent, is+

An atomizer comprising the casting d havin g a partition forming twochambers, a steamsupply pipe-communicating with one of said chambers, avertically-extending steam-outlet pipe from theother chamber having acovering-cap, a discharge-pipe for Water of condensation' from saidsecond chamber, and a needle-yalve controlling the passage of steamthrough an opening in said partition, substantially as described.

, In testimony that I claim the foregoing as my invention I have signedmy name, in presenceof two witnesses, this 9th day of December, 1897.

BRUNO WILLIBALD EMIL GRIEP.
